　特許文献１に示されたかごドアロック装置では、電磁コイルで施錠子を動作させるため、停電した場合には、かごが正規の位置に着床していてもかご内から戸開できず、閉じ込め状態が継続される恐れがあり、バッテリを積載して対応する必要が生じる。 In the car door lock device disclosed in Patent Document 1, the lock is operated by an electromagnetic coil. Therefore, in the event of a power failure, the car cannot be opened from the inside of the car even if it is landed at a proper position, and is locked up. There is a possibility that the state will continue, and it becomes necessary to load a battery and take measures.

　また、特許文献２に示されたかごドアロック装置では、全ての階床に、乗場ドア係合部材の他に解錠用力ムを設置する必要があり、階床数が多い場合に必要となる鉄板の量が多くなり、設置コストも高くなる。 Further, in the car door lock device disclosed in Patent Document 2, it is necessary to install an unlocking force in addition to the landing door engaging member on all floors, which is necessary when the number of floors is large. The amount of iron plates increases and the installation cost also increases.

　さらに、特許文献３に示されたかごドアロック装置では、衝撃に対する誤動作（正常ではない解錠動作）が発生しないように、施錠状態を保持するためのばねの保持力を大きくする必要があり、これにより解錠動作も重くなる。一方、かご側の係合部品が乗場側の係合部品に当接する際に解錠動作をするので、乗場ドアを開放するのに必要な力よりも小さな力で動作することが求められ、保持力の調整が難しい。 Furthermore, in the car door lock device shown in Patent Document 3, it is necessary to increase the holding force of the spring for holding the locked state so as not to cause a malfunction (unusual unlocking operation) against impact, This also increases the unlocking operation. On the other hand, since the unlocking operation is performed when the car-side engaging part comes into contact with the landing-side engaging part, it is required to operate with a force smaller than the force required to open the landing door, and is held. Power adjustment is difficult.

　この発明は、上記のような課題を解決するためになされたものであり、簡単な構成により、いたずらによるこじ開け力及び衝撃に対して誤動作を発生しにくくすることができるエレベータのかごドアロック装置を得ることを目的とする。 The present invention has been made in order to solve the above-described problems, and provides an elevator car door lock device that is less likely to cause a malfunction with respect to a prying force and an impact caused by tampering with a simple configuration. The purpose is to obtain.

　この発明に係るエレベータのかごドアロック装置は、かごドアを閉鎖位置にロックする施錠装置、回動軸を中心として回動可能に前記かごドアに設けられているリンクを有するリンク機構、リンク機構を介してかごドアに設けられており、かつ、施錠位置と、施錠位置よりも戸袋とは反対側の解錠位置との間で水平方向へ変位可能になっている戸当たり側ブレード、戸当たり側ブレードの解錠位置への変位を施錠装置に機械的に伝達して施錠装置を解錠状態にする伝達機構、及びリンクの回動軸に対して戸当たり側ブレードとは反対側に設けられているバランスウェイトを備え、かごが着床位置にあるときにかごドアが戸袋側へ移動することにより、戸当たり側ブレードが、乗場ドアに設けられた乗場ドア係合部材に当接して解錠位置へ変位するとともに、バランスウェイトが戸当たり側ブレードとは反対側へ変位するようになっている。 An elevator car door lock device according to the present invention includes a locking device that locks a car door in a closed position, a link mechanism that has a link provided on the car door so as to be rotatable about a rotation shaft, and a link mechanism. Door side blades, which are provided on the car doors, and are horizontally displaceable between the locked position and the unlocked position on the opposite side of the door pocket from the locked position. A transmission mechanism that mechanically transmits the displacement of the blade to the unlocking position to the locking device to bring the locking device into an unlocked state, and is provided on the opposite side of the door contact side blade with respect to the rotation shaft of the link. When the car is in the landing position, when the car door is moved to the door pocket side, the door end blade comes into contact with the landing door engaging member provided on the landing door and is unlocked. Strange While, balance weight is adapted to be displaced to the opposite side of the door stop side blade.

　この発明のエレベータのかごドアロック装置は、かごドアの開動作に対して、バランスウェイトの逆動作により、戸当たり側ブレードにかかる慣性力が仰制されるので、リンク機構を介した施錠装置への作用力を減少させることができ、簡単な構成により、いたずらによるこじ開け力及び衝撃に対して誤動作を発生しにくくすることができる。 In the elevator car door lock device according to the present invention, the inertia force applied to the door stop side blade is controlled by the reverse operation of the balance weight with respect to the opening operation of the car door. The operation force can be reduced, and with a simple configuration, it is possible to make it difficult to cause a malfunction with respect to the pry-off force and impact caused by mischief.

　揺動部材５６の第２の端部と第２の上部リンク５４の第２の端部との間には、第２の連結棒５９が連結されている。戸袋側ブレード５３は、重力又はばね力の作用により戸当たり側へ付勢されている。 A second connecting rod 59 is connected between the second end of the swing member 56 and the second end of the second upper link 54. The door pocket blade 53 is biased toward the door stop side by the action of gravity or spring force.

　第１のかごドア１２ａが閉鎖位置にあるときには、揺動部材ローラ５７がガイド部材５８に当接しており、戸袋側ブレード５３はインターロックローラ２９，３０から離れている。 When the first car door 12a is in the closed position, the swinging member roller 57 is in contact with the guide member 58, and the door blade 53 is separated from the interlock rollers 29 and 30.

　これに対して、第１のかごドア１２ａが開方向へ移動されると、揺動部材５６が図３の時計方向へ揺動されるとともに、戸袋側ブレード５３が戸当たり側ブレード４６側へ変位し、ブレード４６，５３の間隔が小さくなり、インターロックローラ２９，３０がブレード４６，５３間に把持される。 On the other hand, when the first car door 12a is moved in the opening direction, the swinging member 56 is swung in the clockwise direction in FIG. 3 and the door pocket blade 53 is displaced toward the door-contacting blade 46. Then, the interval between the blades 46 and 53 is reduced, and the interlock rollers 29 and 30 are gripped between the blades 46 and 53.

　なお、戸袋側ブレード５３を水平方向へ変位可能とする構成は必須ではなく、戸袋側ブレード５３をかごドア１２に固定してもよい。 It should be noted that the configuration in which the door pocket blade 53 can be displaced in the horizontal direction is not essential, and the door pocket blade 53 may be fixed to the car door 12.

　図４は図３のＩＶ－ＩＶ線に沿う断面図、図５は図３のＶ－Ｖ線に沿う断面図である。かご８が着床したとき、戸当たり側ブレード４６は、インターロックローラ２９，３０の戸当たり側に配置されており、戸袋側ブレード５３は、インターロックローラ２９，３０の戸袋側に配置されている。 4 is a cross-sectional view taken along line IV-IV in FIG. 3, and FIG. 5 is a cross-sectional view taken along line VV in FIG. When the car 8 is landed, the door stop side blade 46 is disposed on the door stop side of the interlock rollers 29 and 30, and the door pocket side blade 53 is disposed on the door pocket side of the interlock rollers 29 and 30. Yes.

　また、インターロックローラ２９，３０は、真上から見て、かご敷居線（かご敷居の乗場側端面）Ｌ１と乗場敷居線（乗場敷居のかご側端面）Ｌ２との間に配置されている。さらに、リンク４７，４８，５４，５５、戸当たり側ブレード４６のリンク４７，４８との連結部、及び戸袋側ブレード５３のリンク５４，５５との連結部は、真上から見て、かご敷居線Ｌ１の内側（かご８側）に配置されている。 Further, the interlock rollers 29 and 30 are disposed between the car sill line (the end face on the landing side of the car sill) L1 and the landing sill line (the end face on the car side of the landing sill) L2 when viewed from directly above. Further, the link 47, 48, 54, 55, the connecting portion of the door stop side blade 46 with the links 47, 48, and the connecting portion of the door pocket side blade 53 with the links 54, 55 are seen from above, and the car sill. It is arranged inside the line L1 (the car 8 side).

　次に、動作について説明する。かごドア１２が全閉位置にあるときは、図４及び図５に示すように、戸当たり側ブレード４６は施錠位置に位置しており、インターロックローラ２９，３０から離れている。また、可動施錠子４３は施錠状態となっている。 Next, the operation will be described. When the car door 12 is in the fully closed position, as shown in FIGS. 4 and 5, the door stop side blade 46 is located in the locking position and is separated from the interlock rollers 29 and 30. The movable lock 43 is in a locked state.

　図６は図３のかごドア１２が開方向へ少し移動した状態を示す正面図、図７は図６のＶＩＩ－ＶＩＩ線に沿う断面図である。かごドア１２が開方向へ移動し始めると、戸当たり側ブレード４６の当接面（第１のかごドア１２ａの正面に直角な面）がインターロックローラ２９，３０に当接し、戸当たり側ブレード４６が解錠位置に変位される。これにより、可動施錠子４３が解錠状態になる。また、インターロックラッチ２８が揺動され、乗場ドア１４のインターロック装置２６も解錠状態になる。 6 is a front view showing a state in which the car door 12 of FIG. 3 is slightly moved in the opening direction, and FIG. 7 is a cross-sectional view taken along the line VII-VII of FIG. When the car door 12 starts to move in the opening direction, the contact surface of the door contact side blade 46 (the surface perpendicular to the front surface of the first car door 12a) contacts the interlock rollers 29 and 30, and the door contact side blade 46 is displaced to the unlocking position. Thereby, the movable lock 43 is in an unlocked state. Further, the interlock latch 28 is swung, and the interlock device 26 of the landing door 14 is also unlocked.

　図８は図６のかごドア１２が開方向へさらに移動した状態を示す正面図、図９は図８のＩＸ－ＩＸ線に沿う断面図である。かごドア１２が開方向へさらに移動すると、戸袋側ブレード５３が第１のかごドア１２ａに対して戸当たり側へ移動し、インターロックローラ２９，３０がブレード４６，５３間に把持されて、第１のかごドア１２ａと第１の乗場ドア１４ａとが一体に開動作する。また、第２のかごドア１２ｂ及び第２の乗場ドア１４ｂも同期して開動作する。 8 is a front view showing a state where the car door 12 of FIG. 6 is further moved in the opening direction, and FIG. 9 is a cross-sectional view taken along the line IX-IX of FIG. When the car door 12 further moves in the opening direction, the door bag side blade 53 moves to the door contact side with respect to the first car door 12a, and the interlock rollers 29 and 30 are gripped between the blades 46 and 53, The first car door 12a and the first landing door 14a are integrally opened. Further, the second car door 12b and the second landing door 14b are also opened synchronously.

　一方、何等かの異常によりかご８がドアゾーン外に停止した状態で、かご室１１内の乗客がかごドア１２をこじ開けようとした場合、図１０に示すように、戸当たり側ブレード４６にインターロックローラ２９，３０が当接しないため、戸当たり側ブレード４６は施錠位置に位置したままであり、可動施錠子４３も施錠状態のままとなる。このため、第１のかごドア１２ａが僅かに戸袋側へ移動した時点で可動施錠子４３が固定施錠子４２に当接し、かごドア１２の開方向への移動が阻止される。 On the other hand, when the passenger in the car room 11 tries to open the car door 12 with the car 8 stopped outside the door zone due to some abnormality, the door-stop blade 46 is interlocked as shown in FIG. Since the rollers 29 and 30 do not come into contact with each other, the door stop side blade 46 remains in the locking position, and the movable locking element 43 also remains in the locked state. Therefore, when the first car door 12a slightly moves to the door pocket side, the movable lock 43 abuts against the fixed lock 42, and the movement of the car door 12 in the opening direction is prevented.

　このようなかごドアロック装置では、かごドア１２の開動作に対して、バランスウェイト５１の逆動作により、戸当たり側ブレード４６にかかる慣性力が仰制されるので、第１の平行リンク機構４５を介した施錠装置４１への作用力を減少させることができ、簡単な構成により、いたずらによるこじ開け力及び衝撃に対して誤動作（正常ではない解錠動作）を発生しにくくすることができる。 In such a car door lock device, the inertial force applied to the door contact side blade 46 is controlled by the reverse operation of the balance weight 51 with respect to the opening operation of the car door 12, and therefore the first parallel link mechanism 45. It is possible to reduce the acting force on the locking device 41 via the, and with a simple configuration, it is possible to make it difficult to generate a malfunction (unusual unlocking operation) with respect to a prying force and an impact caused by mischief.

　ここで、かごドア１２が開閉動作する際の第１の平行リンク機構４５及びバランスウェイト５１の慣性力による前記回動軸周りのモーメントと、かごドア１２が開閉動作する際に戸当たり側ブレード４６の第１の平行リンク機構４５への接続位置に付加される戸当たり側ブレード４６の慣性力による回動軸４７ａ，４８ａ周りのモーメントとが釣り合う（ほぼ釣り合っている状態も含む）ように、バランスウェイト５１の重さ等を設定するのが好適である。 Here, the moment around the rotation axis due to the inertial force of the first parallel link mechanism 45 and the balance weight 51 when the car door 12 is opened and closed, and the door contact side blade 46 when the car door 12 is opened and closed. So that the moments around the rotation shafts 47a and 48a due to the inertial force of the door-contacting blade 46 added to the connection position to the first parallel link mechanism 45 are balanced (including a state where they are substantially balanced). It is preferable to set the weight of the weight 51 and the like.

　これにより、かごドアの開閉動作時に、慣性力による回動軸４７ａ，４８ａの周りのモーメントを積極的に小さくすることができ、いたずらによるこじ開け力及び衝撃に対して誤動作をより確実に発生しにくくすることができる。 As a result, when the car door is opened and closed, the moment around the rotating shafts 47a and 48a due to the inertial force can be actively reduced, and it is less likely to cause a malfunction with respect to the pry-off force and impact caused by mischief. can do.

　支持板４４には、戸当たり側ブレード６２の可動範囲を制限する一対のストッパ６４ａ，６４ｂが設けられている。戸当たり側ブレード６２は、重力又はばね力の作用により可動範囲の戸袋側、即ち施錠位置側へ常時付勢されている。 The support plate 44 is provided with a pair of stoppers 64a and 64b that limit the movable range of the door stop side blade 62. The door stop side blade 62 is always urged toward the door pocket side of the movable range, that is, the locking position side by the action of gravity or spring force.

　実施の形態１では、戸当たり側ブレード４６のインターロックローラ２９，３０との当接面（第１のかごドア１２ａの正面に直角な面）が戸当たり側ブレード４６の戸袋側端部に設けられているが、実施の形態２では、戸当たり側ブレード６２のインターロックローラ２９，３０との当接面が、戸当たり側ブレード６２の戸当たり側の端部に設けられている。 In the first embodiment, the contact surface of the door stop side blade 46 with the interlock rollers 29 and 30 (the surface perpendicular to the front surface of the first car door 12a) is provided at the end of the door stop side blade 46 on the door pocket side. However, in the second embodiment, the contact surface of the door contact side blade 62 with the interlock rollers 29 and 30 is provided at the end of the door contact side blade 62 on the door contact side.

　実施の形態２のバランスウェイト６５は、第１の下部リンク６３の第２の端部（回動軸４８ａに対して戸当たり側ブレード４６とは反対側の端部）に一体に設けられている。即ち、バランスウェイト６５は、第１の下部リンク６３を戸当たり側ブレード６２とは反対側へ延長した部分である。また、バランスウェイト６５の質量及び長さは、実施の形態１と同様に、第１のかごドア１２ａの開閉動作時の戸当たり側ブレード６２の慣性力をキャンセルできるように適切に設計されている。 The balance weight 65 of the second embodiment is integrally provided at the second end of the first lower link 63 (the end opposite to the door-closing blade 46 with respect to the rotation shaft 48a). . That is, the balance weight 65 is a portion obtained by extending the first lower link 63 to the side opposite to the door stop side blade 62. Further, the mass and length of the balance weight 65 are appropriately designed to cancel the inertial force of the door contact side blade 62 during the opening / closing operation of the first car door 12a, as in the first embodiment. .

　回動軸４７ａ，６３ａ及びバランスウェイト６５は、真上から見て、戸当たり側ブレード６２のインターロックローラ２９，３０との当接面よりも戸袋側に配置されている。また、戸当たり側ブレード６２の当接面以外の部分は、真上から見て、かご敷居線Ｌ１の内側（かご８側）に配置されている。 The rotation shafts 47a and 63a and the balance weight 65 are arranged on the door pocket side from the contact surface of the door stop side blade 62 with the interlock rollers 29 and 30 when viewed from directly above. Further, the portion other than the contact surface of the door contact side blade 62 is disposed on the inner side (the car 8 side) of the car sill line L1 when viewed from directly above.

　即ち、リンク４７，６３は、真上から見て、かご敷居線Ｌ１の内側、かつ戸当たり側ブレード６２の当接面よりも戸袋側で、戸当たり側ブレード６２に回転可能に連結されている。他の構成は、実施の形態１と同様である。 That is, the links 47 and 63 are rotatably connected to the door stop side blade 62 on the inner side of the car sill line L1 and on the door pocket side of the contact surface of the door stop side blade 62 when viewed from directly above. . Other configurations are the same as those in the first embodiment.

　このようなかごドアロック装置では、かごドア１２の開動作に対して、バランスウェイト５１の逆動作により、戸当たり側ブレード６２にかかる慣性力が仰制されるので、第１の平行リンク機構６１を介した施錠装置４１への作用力を減少させることができ、簡単な構成により、いたずらによるこじ開け力及び衝撃に対して誤動作（正常ではない解錠動作）を発生しにくくすることができる。 In such a car door lock device, the inertial force applied to the door stop side blade 62 is controlled by the reverse operation of the balance weight 51 with respect to the opening operation of the car door 12, so the first parallel link mechanism 61. It is possible to reduce the acting force on the locking device 41 via the, and with a simple configuration, it is possible to make it difficult to generate a malfunction (unusual unlocking operation) with respect to a prying force and an impact caused by mischief.

　実施の形態３．
　次に、図１４はこの発明の実施の形態３によるエレベータのかごドアロック装置を示す正面図である。かごドアフレーム３１と第１のかごドア１２ａとの間には、第１のかごドア１２ａを閉鎖位置にロックする施錠装置７１が設けられている。施錠装置７１は、かごドアフレーム３１に回動可能に設けられたかご側施錠子７２と、第１のかごドア連結金具３８に設けられたドア側施錠子７３とを有している。 Embodiment 3 FIG.
Next, FIG. 14 is a front view showing an elevator car door lock device according to Embodiment 3 of the present invention. Between the car door frame 31 and the first car door 12a, there is provided a locking device 71 for locking the first car door 12a in the closed position. The locking device 71 has a car-side locker 72 that is rotatably provided on the car door frame 31, and a door-side locker 73 that is provided on the first car door connecting bracket 38.

　ドア側施錠子７３は、第１のかごドア連結金具３８の上端部を上方へ延長することにより、第１のかごドア連結金具３８の一体に形成されている。施錠装置７１を解錠しないでかごドア１２を開こうとすると、ドア側施錠子７３がかご側施錠子７２に当接して、開方向へのかごドア１２の移動が阻止される。 The door side lock element 73 is formed integrally with the first car door connecting bracket 38 by extending the upper end portion of the first car door connecting bracket 38 upward. If the car door 12 is opened without unlocking the locking device 71, the door side lock element 73 comes into contact with the car side lock element 72, and the movement of the car door 12 in the opening direction is prevented.

　第１のかごドア連結金具３８には、解錠レバー７４が回動可能に設けられている。解錠レバー７４の第１の端部には、第１の連結棒５０の上端部が回動可能に連結されている。解錠レバー７４の第２の端部には、解錠ローラ７５が設けられている。実施の形態３の伝達機構７６は、第１の連結棒５０、解錠レバー７４及び解錠ローラ７５を有している。他の構成は、実施の形態１と同様である。 The first car door coupling bracket 38 is provided with an unlocking lever 74 so as to be rotatable. The upper end of the first connecting rod 50 is rotatably connected to the first end of the unlocking lever 74. An unlocking roller 75 is provided at the second end of the unlocking lever 74. The transmission mechanism 76 according to the third embodiment includes the first connecting rod 50, the unlocking lever 74, and the unlocking roller 75. Other configurations are the same as those in the first embodiment.

　次に、動作について説明する。かごドア１２が全閉位置にあるときは、図１４に示すように、戸当たり側ブレード４６は施錠位置に位置しており、かご側施錠子７２は施錠状態（水平状態）となっている。 Next, the operation will be described. When the car door 12 is in the fully closed position, as shown in FIG. 14, the door stop side blade 46 is located in the locking position, and the car side locking element 72 is in the locked state (horizontal state).

　図１５は図１４のかごドア１２が開方向へ少し移動した状態を示す正面図、図１５のかごドア１２が開方向へさらに移動した状態を示す正面図である。かごドア１２が開方向へ移動し始めると、戸当たり側ブレード４６がインターロックローラ２９，３０に当接し、戸当たり側ブレード４６が解錠位置に変位される。 FIG. 15 is a front view showing a state where the car door 12 of FIG. 14 is slightly moved in the opening direction, and a front view showing a state where the car door 12 of FIG. 15 is further moved in the opening direction. When the car door 12 starts to move in the opening direction, the door contact side blade 46 comes into contact with the interlock rollers 29 and 30, and the door contact side blade 46 is displaced to the unlocked position.

　これにより、解錠レバー７４が図の反時計方向へ回動され、解錠ローラ７５によりかご側施錠子７２が図の時計方向へ回動されて解錠状態になる。そして、図１６に示すように、かご側施錠子７２の先端の係合部７２ａをドア側施錠子７３が通過する。解錠ローラ７５が接していない状態では、重力又はばね力の作用により、かご側施錠子７２は水平状態に戻される。また、かご側施錠子７３の係合部７２ａ及びドア側施錠子７３にはそれぞれ傾斜面が設けられており、かごドア１２の閉動作時には、傾斜面によりかご側施錠子７２を回動させて解錠状態にすることができる。 Thereby, the unlocking lever 74 is rotated in the counterclockwise direction in the figure, and the car side locking element 72 is rotated in the clockwise direction in the figure by the unlocking roller 75 to be in the unlocked state. Then, as shown in FIG. 16, the door side locking element 73 passes through the engaging portion 72 a at the tip of the car side locking element 72. In a state where the unlocking roller 75 is not in contact, the car-side locker 72 is returned to the horizontal state by the action of gravity or spring force. Further, the engaging portion 72a of the car-side locker 73 and the door-side locker 73 are provided with inclined surfaces, respectively, and when the car door 12 is closed, the car-side locker 72 is rotated by the inclined surface. Can be unlocked.

　一方、何等かの異常によりかご８がドアゾーン外に停止した状態で、かご室１１内の乗客がかごドア１２をこじ開けようとした場合、図１７に示すように、戸当たり側ブレード４６にインターロックローラ２９，３０が当接しないため、戸当たり側ブレード４６は施錠位置に位置したままであり、かご側施錠子７２も施錠状態のままとなる。このため、第１のかごドア１２ａが僅かに戸袋側へ移動した時点でドア側施錠子７３がかご側施錠子７２に当接し、かごドア１２の開方向への移動が阻止される。 On the other hand, when the passenger in the car room 11 tries to open the car door 12 with the car 8 stopped outside the door zone due to some abnormality, the door-stop blade 46 is interlocked as shown in FIG. Since the rollers 29 and 30 do not come into contact, the door stop side blade 46 remains in the locked position, and the car side lock 72 also remains in the locked state. For this reason, when the first car door 12a slightly moves to the door pocket side, the door-side lock element 73 comes into contact with the car-side lock element 72, and the movement of the car door 12 in the opening direction is prevented.

　このようなかごドアロック装置では、回動可能なかご側施錠子７２をかごドアフレーム３１に設けたので、施錠確認用のスイッチ（電気接点）を適用する場合に、スイッチを第１のかごドア１２ａ側ではなく、かご８側に設けることができ、ケーブルの配線が容易となる。また、かごドア１２の開閉によりケーブルが移動しないので、ケーブルの断線が防止され、信頼性が向上する。 In such a car door lock device, the car-side locker 72 that can be rotated is provided on the car door frame 31. Therefore, when a switch (electrical contact) for locking confirmation is applied, the switch is used as the first car door. It can be provided not on the 12a side but on the car 8 side, which facilitates cable wiring. Further, since the cable does not move by opening and closing the car door 12, the cable is prevented from being disconnected and the reliability is improved.

　なお、実施の形態３の施錠装置７１及び伝達機構７６は、実施の形態２のかごドアロック装置にも適用できる。
　また、この発明のかごドアロック装置が適用されるエレベータのタイプは、図１のタイプに限定されるものではない。例えば、機械室レスエレベータ、２：１ローピング方式のエレベータ、マルチカー方式のエレベータ、又はダブルデッキエレベータ等にも、この発明は適用できる。 The locking device 71 and the transmission mechanism 76 of the third embodiment can also be applied to the car door lock device of the second embodiment.
The elevator type to which the car door lock device of the present invention is applied is not limited to the type shown in FIG. For example, the present invention can be applied to a machine room-less elevator, a 2: 1 roping elevator, a multi-car elevator, a double deck elevator, or the like.
